Yesterday, about 24 hours ago, we reported that Nokia has released its — now rebranded — HERE maps for iOS, making it available for iPhone and iPad. Today, 24 hours later, the application is already the fourth application in the top free iPhone app list on iTunes, way above popular titles like Pandora, Spotify, Twitter, or even some Apple apps.

After iOS 6 removed Google Maps from the system, users of the iPhone 5 — as well as previous version of the iPhone and iPad that were updated to iOS 6 — were left with Apple’s own maps and some alternatives proposed by Apple itself after the initial cartography fiasco. Whether a Google Maps application will arrive (and whether it will be approved and accepted by Apple in the App Store) is yet unknown but seeing the popularity of Nokia’s application it might be a top-three worthy free software bit.
